AUTOMATIC TUNNEL MONITORING AND MEASURING DEVICE AND METHOD BASED ON FIXED-POINT ITINERANT MEASUREMENT

Disclosed in the present invention are an automatic tunnel monitoring and measuring device and method based on fixed-point itinerant measurement. The device comprises a monitoring trolley capable of freely moving in a tunnel longitudinally, a plurality of automatic tracking identification apparatuses connected to a background processing system are provided on the monitoring trolley, and several monitoring points attached with reflective identifiers are arranged on the surface of a tunnel supporting structure. Under the cooperation between the monitoring trolley and the automatic tracking identification apparatuses, automatic fixed-point itinerant measurement can be performed on the reflective identifiers arranged on the tunnel supporting structure to obtain coordinate information of related monitoring points, and then deformation data of the supporting structure required in a construction process is extracted by calculating the coordinate information, thereby achieving real-time monitoring in all directions a
